Field of the Invention The present invention relates to a pest attractant-preventing acrylic resin film which blocks light having a wavelength to which pests are sensitive from transmitting to the outside, thereby preventing the pests from actively flying by light. And a laminate having the film on the surface. INDUSTRIAL APPLICABILITY The present invention is useful, for example, as a protective film or a protective plate for preventing pest attraction in applications such as lighting covers, show windows, vending machine front panels, and glazing.

For example, an accident in which a flying insect such as a fly or a mosquito is mixed into a product of a food factory is a serious problem in quality control. Recently, factories are often located in suburban areas, and agricultural pests such as planthoppers and leafhoppers generated from surrounding paddy fields and fields are attracted by lights and fly to the factories, causing product contamination. There are many.

ともある。[0003] In addition, pests attracted to evening lights in villas, mountain cottages, suburban restaurants, and the like often fly on window glasses, and have a poor impression on customers. In particular, during the breeding season of termites and the like, they fly in thousands or tens of thousands and hit show windows and the like, which sometimes hinders sales.

り侵入することもある。[0007] For example, when an insect screen is used, it is possible to prevent invasion into the room to some extent, but it is not possible to prevent flying or adhesion to window glass or the like. Therefore, flying pests often fly around the building and invade through gaps, particularly in small gaps such as under aluminum sash rails.

引阻止効果の点でまだ十分でない。[0008] For example, in the case of extermination with an insecticide, secondary adverse effects such as toxicity, product safety and environmental pollution are induced. Further, in the conventional insect repellent light, since the lighting itself is treated, the indoor lighting becomes colored light, which often impairs the habitability. On the other hand, JP-A-9-472
